Hi folks-
I'm trying to use the client/server features of FIO. I have version 2.1.3. The client/server works great for running the specified job file. The problem I am having is with the reporting. I have 96 clients running against a single target and I need to aggregate the results. So I need to either:
1) Get minimal output back, then I can load it up in Excel or whatever and add/average the numbers easily
2) Get a version of group reporting, where the client aggregates all the results for me and just shows totals/averages
I don't think #2 is a feature of FIO client/server so I'm trying to do #1. However, I can't seem to get minimal output back when using client/server (I get it all the time when running locally). See example below. Only the very last part ("disk stats") is in minimal format. Am I doing something wrong? Is this a bug? Is minimal output just not supported for client/server? Thanks!
